We just got some goodies on our team: Xbox 360 HD DVD drives in black! These limited-edition drives were made especially for those of us who helped work on the product, and come along with a black remote control.
All I need now is an Xbox 360 at home to plug it into and I'll be set! (It's no use to me at work as retail drives don't work on Xbox development kits).
Different teams at Microsoft give different things to team members as "Ship-It" awards, and how good they are depends on the coolness of the team and the coolness of the product. Fortunately our team is cool in both regards. My old team (Visual C#) once gave us empty cardboard boxes of the product as a Ship-It award. Not-very-cool-at-all.
Unlike some other Microsoft-internal goodies, we are permitted to sell these, so if you want one you might be lucky and a co-worker could put one on eBay. Or not.
[Update 4/20/07: the rules have changed and in fact we are not allowed to sell these after all]
